Her life is turned upside down as she is stuck right in the middle of this great, yet unknown, war. She will have to go through contrasts of pain and happiness, love and sacrifices, if she wants any chance of surviving this ordeal. And if she thinks that the people from her hell of a school were devils, then wait until she meets the real one.
